How long should you keep the coolant heater plugged in? The answer depends on the outside temperature, the kind of oil you have, and some other things. Instead of trying to list everything here, we ask that you contact your dealer in the area where you'll be parking your vehicle. The dealer can give you the best advice for that particular area. There are several different positions for your shift lever. PARK (P): This gear position locks your front wheels. It is the best position to use when you start your engine because your vehicle cannot move easily. Ensure the shift lever is fully in PARK (P) before starting the engine. Your vehicle has an automatic transaxle shift lock control system. You have to fully apply your regular brakes before you can shift from PARK (P) when the ignition key is in RUN. As you step on the brake pedal while in PARK (P), you may hear a click from the solenoid of the system. This ensures that the system is operating properly. If you cannot shift out of PARK (P), ease pressure on the shift lever - push the shift lever all the way into PARK (P) as you maintain brake application. Then move the shift lever into the gear you wish. See Shifting Out of Park (P) on page 2-41. Automatic Transaxle Operation Maximum engine speed is limited when you are in PARK (P) or NEUTRAL (N), to protect driveline components from improper operation. 2-34
